+title: Checkbox
+description:
+ Lets a person select an independent option, with optional supporting and validation text.
+---
+
+Use `Checkbox` when a person can choose an option independently of nearby controls.
+
+
+
+## States
+
+Use `defaultSelected` for an uncontrolled initial value, or pair `isSelected` with `onChange` when
+application state owns the selection. `isIndeterminate` communicates a mixed state, such as a parent
+option whose child options are only partly selected.
+
+
+
+Disabled checkboxes cannot be changed or focused. Read-only checkboxes remain focusable so their
+state is available to keyboard and assistive-technology users. Keyboard navigation shows a
+focus-visible ring; it is intentionally not shown for pointer focus.
+
+
+
+## Size
+
+Use `size` to change the checkbox control without changing its label typography. `medium` is the
+default. Use `small` in compact layouts and `large` where a larger control improves scanning.
+
+
+
+## Description and validation
+
+Pass `description` to clarify an option. Set `isRequired` and `errorMessage` when selection is
+required for form submission.
+
+## Labels with Text
+
+Wrap a checkbox in block `Text` when its label needs a specific text size. The control follows the
+inherited line height, keeping its fixed visual square centred on the first line when the label
+wraps. Outside `Text`, it uses the normal compact control size.
+
+
+
+## Primitive
+
+Use the [Checkbox primitive](/components/primitives/checkbox) to arrange the clickable content,
+control, indicator, description, and error slots yourself.

+---
+title: Checkbox primitive
+description: Lower-level checkbox anatomy for custom composed form controls.
+---
+
+Use the Checkbox primitive when a composed control needs a custom label layout or extra content. For
+normal application forms, use [`Checkbox`](/components/forms/checkbox).
+
+
+
+## Anatomy
+
+`Checkbox` is the React Aria field root. `CheckboxContent` is the clickable label and must contain
+`CheckboxControl`, which centres `CheckboxIndicator`. Place visible label content beside the control
+inside `CheckboxContent`. Use `FieldDescription` and `FieldError` as siblings of `CheckboxContent`
+for the standard supporting and validation semantics.
